A new study gives insight into the prevalence of nitrogen-fixing trees in tropical rainforests and calls into question prevailing hypotheses for why they are so much more abundant than in temperate forests. Levels of soil nutrients such as nitrogen and phosphorus can significantly affect forests’ ability to gain biomass and effectively absorb and capture carbon…

The most extensive land-based study of the effect of drought on Amazonian rainforests to date has shown that a recent drought completely shut down the Amazon Basin’s carbon sink. Previous research has suggested that the Amazon – the most extensive tropical forest on Earth – may be gradually losing its capacity to take carbon from…
